Letters Patent N 99,784, dated February 15,1870.

The Schedule referred 'to Ln these Letters Patent and making part of the same To whom it may concern:

Know all me'n 'that I, PHILnTUs W. Noanrs, of De troit, inthe county of Wayne, and State of Michigan,

have invented a new and useful Improvement in an Ax and Grabber Combined; and I do declare that the following is a true and accurate description tliereot`,'

reference being had to the accompanying drawings and lto the letters of reference marked thereon, and being a part of this specificat-ibn.

Most of the tools usually, sold as grub-books or'bushhooks are so constructed that the operator is compelled to throw the point of the hook behind the grub to be cut, and then by a pulling jerk cutit o.' The eye or socket for the insertion of the handle is always circular in form, compellingr the use of a round handle, which, as the implement has its greatest weight near the point and on one side of the center, allows it.

,and gives it a constant tendency to turn in the hand of the operator. In clearing land with them the 0perato'r isobliged` to use two distinct and separate tools, viz: an ax for chopping when necessary, anda grubber for its legitimate use., y'

Theobject of t-his'invention is to obviate the necessity ot' carrying and using two different implements, by combining the two into one tool, and arranging the eye so that an ordinary :tx-handle maybe used, wherebythe movements of the implement can be accurately governed, and. all tendency to turn in the hand is avoided. By combining the two, (using a longer or shorter bit to the ax, according to the Work to be A done.) I make an implement by which the weight of the tool and the velocity of the blow will enable the operator to cut off the root or grub, instead of' being compelledto cut 'it otf by brute force, as is tbe case in bush-hooks of the ordinary construction, while the ax-bit enables him to cut small trees with as much case as he could with an'ax separate.

In the annexed drawings- A represent-s the ax part of my device, made in the usual form of an American chopping-ax, except that the poll -is rather heavierlthau iu such axes, for thel purpose of counterbalancing the weight of theliook hereinafter described. This ax is provided with an' elliptical eye passing entirely through it, the\longest direct-ion of which is in thevertical line of the alv, and the smallest end of which is downward.

B represents the hook, extending beyond and beingV Y a continuation of the ax between the bottom ot the eye and the bit, the edge of which hook is a continuation of the line of the bit, being snbstantia'llystraight. to the ax proper, and continuing beyond said ax proper in. a' straight line a distance about as great as the length of the bit of the ax proper, when `it curves downwardabout a couple of inches, and terminates in a sharp point. The back of this hook correspnds to the edge of it, except that it has a greater lturn at the end, so that the hook may be strong at its point. v

To this device a usual :nu-handle,- C, is secured in any ordinary manner.

The drawing shows the hook longer than I usually make it in the manufacture of this implement.

The great merit of my device consists in its effectiveness. It enables the operator by reason of percussive blows to sever roots as weil as could be done wit-h ordinary axes, aud yet permits him to use the hook also, by drawing toward him iu cutting small .roots and twigs, and by using it as a lever, wit-h the XVitnesses:
